Connection Possibilities
The 750 Series Module PCB Operates as an Interface ‘Hub’ on the Addressable 2-Wire Highway.

Note that one 2-Wire addressable highway running S protocol can support up to 32 modules. Each module
can have up to 8 connected devices. IGD Configuration software is used to configure the module PCB to switch
devices on and off and set addresses (see Tocsin 650/750 Manual). If the connected devices have already been
configured then the base address can be set from which all other module addresses will sequentially follow. This is
described later in this manual. Device addresses indicated in the table are typical but can be individually set.
Max Simulations = 8 (Pellistor, T102, In1, In2, E stop*, Key Switch*, Relay, Sounder*).
Max Inputs = 6 (Pellistor, T102, In1, In2, E Stop*, Key Switch*).
Max Outputs = 4 (Out1, Out2, Relay, Sounder*).
